B&K amp parts source

Hi All,

I have a B&K Ref 2220 which sounds very nice with the Thiel CS 3.5 speakers in my secondary system. However, the power on button has become unreliable, sometimes requiring dozens of presses to turn the amp off. I have repeatedly contacted ATI who aquired B&K and am told, " We have all their parts, but nothing is organized so we can't find it for you."
I had my local electronics shop call ATI, and they got the same response. My local tech commented that the power switch on my amp looked identical to ones he had seen on other B&K amps, so it should not be a rare part. What I am hoping you can help with is where, other than ATI, might I get one? Perhaps a dealer who stocked a lot of B&K amps and has one?
BTW my local tech, who I think is highly competent, cleaned and lubricated my switch, but the problem was not improved.
Thanks in advance!

I've always prefered toggle switches that are much more durable than OP described. If there's a possibility to connect toggle switch onto the same socket(just measure the size) you can go for it. It will perform the same function. In my case I simply use master switch for my equipment from Panamax power supply and technically you can simply short that switch and not use it at all.

You might wish to contact Byston as they used a similar on/ off switch. The only question, is the hole size for the button...

can you remove the existing switch and get a part number? I can't imagine that it's not an off the shelf part. The button that shows on the outside may be special to B&K, but the switch itself is likely standard and available at Mouser

Drjay, the original switch is round, which should make installing a replacement easier, although you may need to do some minor modification to get the new switch to fit. Digi-Key has a selection of 16A 120V round pushbutton switches, and one 20A 120V round pushbutton switch in stock. You may also be able to use a toggle switch in place of a pushbutton, if it should come down to that.

Thanks for all the help so far.
It looks like my best bet is to call Eastern Elete AV and hope they have the B&K style switch. I took the cover off the amp and the switch is not at all like any of the generic ones which Gbart kindly provided a link to. It is bolted to the back of the faceplate with two small allen bolts with the connection lugs coming out the top.
I will call Eastern Elete AV tomorrow and hope they have it. If anyone has any other leads as to who might have one I would greatly appreciate that info since it doesn't look like a generic one will do.
As an aside, I had no idea as to the variety and options of switches that are in existance before visiting the digikey web site. Wow!
